The messaging app Signal is described by security professionals as utilizing the gold standard of cryptography. Unlike many competitors, its default is end-to-end encryption — and on top of that, the app minimizes the amount of information it stores about users. This makes it a powerful communication tool for those seeking a private and secure means of chatting, whether it’s journalists and their sources, activists and human rights defenders, or just ordinary people who want to evade the rampant data-mining of Big Tech platforms.
Signal continues to introduce privacy-enhancing features such as usernames that can be used in lieu of phone numbers to chat with others — preventing others from finding you by searching for your phone number. But the app still requires users to provide a working phone number to be able to sign up in the first place.
For privacy-conscious individuals, this can be a problem.
In response to subpoena requests, Signal can reveal phone numbers. Relying on phone numbers has also led to security and account takeover incidents. Not to mention that the phone number requirement costs Signal more than $6 million annually to implement.
Signal insists on its site that phone numbers are a requirement for contact discovery and to stymie spam. (Signal did not respond to a request for comment). Other encrypted messaging platforms such as Session and Wire do not require phone numbers.
There are some ways around Signal’s phone number policy that involve obtaining a secondary number, such as using temporary SIM cards, virtual eSIMs, or virtual numbers. But these approaches involve jumping through hoops to set up anonymous payment measures to procure the secondary numbers. And sometimes they don’t work at all (that was my experience when I tried using a Google Voice number to sign up for Signal).
I wanted a way to get a Signal account without leaving any sort of payment trail — a free and anonymous alternative. And thus began my long and tedious journey of registering Signal with a pay phone.
Finding a Pay Phone
The first step was actually finding a pay phone, a task which is dismally daunting in 2024.
The Payphone Project lists around 750,000 pay phones, but after attempting to cross-check a sampling of the hundreds of alleged pay phones in my town with Google Street View and Google Earth satellite images, I came to the quick realization that the list was woefully outdated. Many of these phones no longer exist. A Google Maps search for pay phones in my area brought up of a half-dozen pins. Using Street View, I found that four locations seemed to have something resembling a pay phone box. Trekking out to them, however, revealed that one no longer had a pay phone, though discoloration of the store façade revealed the precise spot the pay phone used to be; another pay phone looked like it had been the victim of a half-hearted arson attack; the third and fourth lacked dial tones.
Asking on a community subreddit resulted in suggestions that once again led me to places without any working pay phones, or posts berating me for needing a pay phone in 2024 and inquiring about the legality of the endeavors I wished to pursue which would necessitate pay phone usage.
Failing at finding a functional pay phone through a systemic approach, I resorted to brute opportunism — keeping my eyes peeled for pay phones as I went through the dull drudgery of a modern life made ever bleaker by the lack of public phone access.
